两种散打腾空转身后摆腿打击效果三维运动学比较研究

Comparative Study of Hitting Effect on Two Different Techniques Jump and Sweep Kick with Body Turn Base on Three Dimensional Kinematics

运用三维运动学的方法,通过对影响打击效果的两种不同技术腾空转身后摆腿打击时间、方向、速度和隐蔽性三维数据对比分析,得出转膝前旋脚跟技术腾空转身后摆腿打击效果好,并进一步从技术细节方面进行深入探讨,分析出缩短打击时间、提高打击速度和隐蔽性的细节技术,目的是提高腾空转身后摆腿动作质量,促进腾空转身后摆腿在散打比赛中的常态使用,使其不再成为少数运动员专属技术或独门绝技在散打比赛中运用,促进散打比赛技术应用的全面性,提高散打比赛的观赏性。通过分析得出转膝前旋脚跟技术腾空转身后摆腿打击效果好于不转膝前旋脚跟技术腾空转身后摆腿;转膝前旋脚跟技术腾空转身后摆腿与不转膝前旋脚跟技术腾空转身后摆腿在打击方向方面差距较小,两种技术都显示出非常高的横击水平;转膝前旋脚跟技术的技术优势在于转膝前旋脚跟、打击腿屈膝提膝、向打击点侧前方展髋蹬伸,利用小腿鞭打打击目标,有效缩短腾空转身后摆腿打击脚空中运行打击时间,提高打击速度和隐蔽性。

By three dimension motion data analysis in this study,it is confirmed that the hitting effect of the technique of knees turn and heels forward turn is good through contrast analysis of three dimension data about the fight against time,the strike direction,the strike speed and hit concealment of jump and sw eep kick with body turn tw o different techniques,and get the technical details to improve the effect of blow with deep research. The purpose is to improve the appreciation of the sanda competition through improving the quality of the action of jump and sw eep kick with body turn and letting more and more athletes use it successfully. The conclusion is that the blow effect of the technique of knees turn and heels forward turn is good,the strike direction is consistent and with good lateral strike level,the technical advantage is knees turn and heels forward turn and knee left with leg bent with calf whipped to hitting target to shorten the fight time of the kick foot flying,improve the blow speed and improve the concealment of the blow.
